Value Collection B220 32 300 Malleable Iron Coupling 1-1/4 in

Product Description

The VALUE COLLECTION B220 32 300# is a black malleable iron threaded coupling rated for Class 300 service at up to 1500 psi. This fitting connects two sections of threaded pipe in a straight run, maintaining a continuous flow path with no change in direction or diameter. The black finish comes from a standard oil or lacquer coat applied after casting, suited for gas distribution, fire protection, and industrial piping systems. Licensed plumbers, pipefitters, and mechanical contractors are the typical installers. At 1.63 pounds and sized for 1-1/4-inch pipe, this coupling fits into tight spaces while delivering the pressure rating required for demanding applications.

This coupling is used in residential and commercial black iron gas piping, fire suppression systems, and industrial fluid distribution lines where Class 300 pressure ratings are required. The threaded end connections conform to multiple international standards including ABNT, EN 10242, FM Approved, GB/T 3287, GB/T 7306.2, ISO 7/1, and cULus, making it suitable for projects with strict code compliance requirements. Installers working on natural gas distribution headers, compressed air headers, or sprinkler supply mains will find this fitting appropriate for those service conditions.

Installation Notes

Installation should be performed by a licensed pipefitter, plumber, or mechanical contractor in accordance with applicable codes such as the IFGC, IPC, or NFPA 13 for fire suppression work. Shut off gas or fluid supply and depressurize the system fully before disassembling or threading any fitting. Apply an appropriate thread sealant or PTFE tape rated for the service medium before making up the joint. Do not over-tighten threaded connections, as this can crack malleable iron fittings.
